StonyLab Glass Short Stem Powder Funnel with 100 mm Top O.D. and 24/40 Inner Joint Filter Funnel Glass Funnel

Feels solid and of good quality no imperfections in the glass work. Haven't used yet but will be exposed to cold and hot temps. So as for how shock resistant it is I don't know.

Primarily used to fill 2&3 necked boiling flasks with powder liquid or prills. It works well.

good manufacturing, good seal. I use it for pouring boiling liquids- no leaks.

No problems so far. Good quality.

Works well holds up under heat and is sturdy.

This is good quality glass. Just note that it uses a angular interface bulge ground glass joint, not the arc bulge joint that most other companies use, and needs a different keck clamp.

Perfect for adding liquid to a 24/40 Flask..Fast delivery, all good...

This funnel is fully functional and works well in that regard. However it thin walled and is made of cheap glass that shatters easily.Spend a little more and get a more resilient brand!

Schön und gut.

Llegó bien

Conforme à la description et arrivé rapidement, c'est une habitude les produits Stony lab sont de très bonne qualité, rien n'y adhère, facile à nettoyer à l'eau distillée, convient parfaitement à des synthèses de solvants. C'est un très bon produit.

I was looking for a funnel that was made of glass because I transfer cosmetic mixes into bottles. I wanted something that I could sterilize and would not react with the chemicals I use. Excellent item and prompt service. Will order from StonyLab if the chance arises again.

Matériel de chimie de très bonne qualité pour un prix abordable . Absolument rien à redire. Je recommande à tous ceux qui sont intéressés.
